No one ever said they want students to go to UCF and then leave Florida forever, but based on other things that they did say, it was clear they do need students to practice elsewhere to get their name know; whether that be for residence, fellowship, or as an attending.
I'm not sure stating either makes that much of a difference and I think everyone is over thinking my initial comment. Basically if you have family ties, great, but you're still considered OOS and they only accept so many (though SixStringPsych's comment is relevant). And saying you're willing to practice elsewhere could come off as trying to hard or over thinking their mission. State what comes naturally from the secondary prompts and don't try to force yourself into the mold you think they want.
Also, the main secondary prompt last year was basically 'tell me about yourself' so the 'is there anything else' is kinda irrelevant in this case as anything you think is important should come out there IHMO.
